The average numeric rating scale (NRS) of ≥ 3 was used in all patients at admission. We recorded average and worst NRS in a 24-hour period, and daily narcotic doses before SBRT, followed by weekly for 1 month and monthly for 3 months.Results: A total of 23 patients in the SBRT group and 12 under SBRT+CPB who met the inclusion criteria were enrolled. All patients in the SBRT+CPB group received CPB within 10 days after SBRT. Pain intensity and narcotic consumption were comparable in both groups at initial assessment. However, a significant decrease (P < 0.05) in average NRS was recorded in the SBRT+CPB group relative to SBRT at 2, 3 and 4 weeks after SBRT. A comparison of daily narcotic consumption with baseline values showed a significant decrease in the SBRT+CPB group at 3 and 4 weeks after SBRT (P < 0.05), while no significant differences were observed in the SBRT group.Conclusion: CPB after SBRT appears to be an effective therapeutic option in patients with LAPC and warrants further evaluation with increased number of patients in prospective clinical trials.Keywords: cancer pain, celiac plexus block, stereotactic body radiotherapy, locally advanced pancreatic cancer |
